The DT of_device.h and of_platform.h date back to the separate
of_platform_bus_type before it as merged into the regular platform bus.
As part of that merge prepping Arm DT support 13 years ago, they
"temporarily" include each other. They also include platform_device.h
and of.h. As a result, there's a pretty much random mix of those include
files used throughout the tree. In order to detangle these headers and
replace the implicit includes with struct declarations, users need to
explicitly include the correct includes.

After commit b8a1a4cd5a98 ("i2c: Provide a temporary .probe_new()
call-back type"), all drivers being converted to .probe_new() and then
03c835f498b5 ("i2c: Switch .probe() to not take an id parameter") convert
back to (the new) .probe() to be able to eventually drop .probe_new() from
struct i2c_driver.

All these drivers have an i2c probe function which doesn't use the
"struct i2c_device_id *id" parameter, so they can trivially be
converted to the "probe_new" style of probe with a single argument.
This is part of an ongoing transition to single-argument i2c probe
functions. Old-style probe functions involve a call to i2c_match_id:
in drivers/i2c/i2c-core-base.c,
/*
* When there are no more users of probe(),
* rename probe_new to probe.
*/
if (driver->probe_new)
status = driver->probe_new(client);
else if (driver->probe)
status = driver->probe(client,
i2c_match_id(driver->id_table, client));
else
status = -EINVAL;
Drivers which don't need the second parameter can be declared using
probe_new instead, avoiding the call to i2c_match_id. Drivers which do
can still be converted to probe_new-style, calling i2c_match_id
themselves (as is done currently for of_match_id).
This change was done using the following Coccinelle script, and fixed
up for whitespace changes:
@ rule1 @
identifier fn;
identifier client, id;
@@
- static int fn(struct i2c_client *client, const struct i2c_device_id *id)

Pull gpio updates from Bartosz Golaszewski:
"Relatively few updates for this release cycle. We have a single new
driver and some minor changes in drivers, more work on limiting the
usage of of_node in drivers and DT updates:
- new driver: gpio-en7523
- dt-bindings: convertion of faraday,ftgpio010 to YAML, new
compatible string in gpio-vf610 and a bugfix in an example
- gpiolib core: several improvements and some code shrink
- documentation: convert all public docs into kerneldoc format
- set IRQ bus token in gpio-crystalcove (addresses a debugfs issue)
- add a missing return value check for kstrdup() in gpio-merrifield
- allow gpio-tps68470 to be built as module
- more work on limiting usage of of_node in GPIO drivers
- several sysfs interface improvements
- use SDPX in gpio-ts4900"

This works around an issue with the hardware where both OE and
DAT are exposed in the same register. If both are updated
simultaneously, the harware makes no guarantees that OE or DAT
will actually change in any given order and may result in a
glitch of a few ns on a GPIO pin when changing direction and value
in a single write.
Setting direction to input now only affects OE bit. Setting
direction to output updates DAT first, then OE.

It's hard for occasional GPIO code reader/writer to know if values 0/1
equal to IN or OUT. Use defined GPIO_LINE_DIRECTION_IN and
GPIO_LINE_DIRECTION_OUT to help them out.
NOTE - for gpio-amd-fch and gpio-bd9571mwv:
This commit also changes the return value for direction get to equal 1
for direction INPUT. Prior this commit these drivers might have
returned some other positive value but 1 for INPUT.
